背景上下文-我正在使用mailchimp3 python库，我试图检索一个人可能会对他们收到的电子邮件进行的一系列操作。通常，它会被弹开，打开或单击。一个人可以单击多次，将其打开多次，否则它只会反弹而已。

我想做的是确定 1.如果有点击与未打开，那么在他们执行的动作列表中，“点击”的索引值是多少？ 2.用管道传输该点击的索引值以获取该点击的时间戳 3.如果没有点击，请执行他们最后一次执行的操作。

现在，我进行此设置只是为了执行某人所做的最后一项操作。我正在尝试使用循环（在下面的代码中间）循环显示其操作列表，确定他们是否单击了，优先考虑将其作为他们的操作的附加值，否则我将采取他们的最后一个操作，

def patient_performance(campaign_id):
    campaign_data = client.reports.email_activity.all(campaign_id=campaign_id,get_all=True)

    patient_campaign = []
    patient_email    = []
    patient_activity = []
    activity_time    = []
    action_list      = []

    for value in campaign_data['emails']:
        #For any unopened or untouched emails. The list will return as empty. Removes any empty email results.
        if len(value['activity']) == 0:
            pass

        else:
            try:
                patient_campaign.append(campaign_id)
                patient_email.append(value['email_address'])

                #Previous code that was working
                #patient_activity.append(value['activity'][-1].get('action'))
                #activity_time.append(value['activity'][-1].get('timestamp'))

                #HERE IS THE NEW CODE I AM TRYING TO INCORPORATE!!!!

                #Summarizes the list of various actions a patient has taken with emails.
                for actions in value['activity']:
                    action_list.append(actions.get('action'))
                    timestamp_list.append(actions.get('timestamp'))


                #Attempting to identify the if a patient clicked.
                for counter,value in enumerate(action_list):
                    if  value == 'click':
                        patient_activity.append(value)
                        activity_time.append(value['activity'][counter].get('timestamp'))
                    else:
                        patient_activity.append(value['activity'][-1].get('action'))
                        activity_time.append(value['activity'][-1].get('timestamp'))


            #Catches any errors.
            except AttributeError:
                pass

    #Appends all results captured for specific campaign. This is fed into a temporary DF which is then appended into the master DF. 
    temp_patient_performance = pd.DataFrame(list(zip(patient_campaign,patient_email,patient_activity,activity_time)),columns = ['campaign','email_address','activity','timestamp'])
    temp_patient_performance = temp_patient_performance.drop(temp_patient_performance[(temp_patient_performance['activity'] == 'bounce')].index)

    print("Retrieved {} patient email results for campaign {}".format(len(temp_patient_performance['email_address']),campaign_id))
    return  temp_patient_performance

这是结果的示例读取结果。每个列表代表一个人，该列表中的多个词典代表进行的多个操作。
